I want to create a distribution certificate in Apple Developer website, I have Administrator privilage, we already have 5 certificates in our account, when I tried to create a certificate the Add iOS Certificate screen is completly disable, not able to select any radio buttons on that.
From the apple document: Each team can have only one active distribution certificate, As the account I am using already had the distribution certificate, I was not able to create one. After deleting the existing distribution certificates, I was able to create a new distribution certificate
